Pivotally connected links 3G und 37 are Ll (l s may be made in the.construction and ar-y under compression attached to leg 28 and anglestrip 2() respectively and constitute a foldable brace for holding theleg 28 extended downwardly from the seat. The crank arms 25 are iiX- Vedly attached to the links 36A so that when shaft 23 is rotated theselinks 36 will be jmoved therewith.

Assuming that the seat is arranged ,for use, as shown in Flg. 2, when itisl desired to fold the seat out of the way, 1t 1s first swung upwardlyand V forwardly about the lower pivots l5 of the legs 14 so as toliftthe feet 30 off of'A the floor.

When the lrear legsassume these positions the front legs lll will also have ar'- rivedbetween the angle strips and the seat 19 will therefore be held insubstantially vertical position' close to and backof the front seat 2,where it will be held by the pressure of springs 11 against levers 13.

When it is desired to set up the seat, the

lower edge of the seat 19, when in theposr tion shown in Fig. 1, ispulled upwardly, whereupon the action hereinbefore described will bereversed and the legs 28 will swing downwardly to the positions shown inFigs. 2v and .4 while the springs ll will be Vplaced and so held by theweight of the seat. v Y' y Y It is tobe understood that :various changesrangement of thevparts ofthe device'withlout departing from the scope.of the inven- ,tion as set forth in the claims.
